SLUG-DELIVERY FOR SLUG CASTING. MAQ HINES.

ntense.

To all whom it may concern Be it known that I, HENRY A. Wish VOOD, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented a new and useful Slug-Deliveryfor Slug-Casting Machines, of which the following is a specification.

This invention relates to the delivery of cast slugs from slug castingmachines.

The principal objects of the same are to provide a delivery which willoperate ctiicient-ly not only with the ordinary slugs produced by linecasting machines but especially so that it can be used with a linecasting machine when the mold of the line casting machine produces aplurality of disconnected slugs at a single operation. Also to provide asimple and el'licient mechanism whereby the slugs will be received andtrimmed and then delivered to-the galley, and to improve the variousfeatures of such adelivery mechanism.

' 'As the invention is designed for use with the ordinary line castingmachines and especially for those in which the line of type is reducedin a plurality of separate slugs, it will be described with particularreference to the latter construction.

Reference is to be had to the accompany:

As this invention is illustrated with special reference to a moldcapable of the pro ducin of a plurality of slugs, certain features ofsuch a mold will first be described.

Referring particularly to Fig. 8, it will be seen that between theliners 13 of the mold there ap )ear a number of dividing pieces Lt whichdivide the mOld up in such a way that a. plurality of separate slugs areSpecification of Letters Patent.

construccl constitutes the subject of a separate invention.

This mold is designed. to be placed on a mold wheel or disk 15 of anyordinary or desired construction and may be manipulated in anyconvenient way as is well understood in this i art.

This invention relates particularly to the dischaige and delivery of theslugs. For this purpose an ejector mechanism is pro vided comprising areciprocating member having a'shaft or stud 17 mounted in be ings 18thereon. U11 this shaft or stud pivotally n'lountcd a plate 19 having ain 20 at the end thereof. A spring 21 on the member 16 operates toyieldingly hold the bar 20 in engagementwith a series of ejector bladesor sections 522. Each of these sections will of course correspondwitlrone of the spaccs in the mold formed beti the dividing pieces l l.In order that th sections may be employed when these spaces are varied,they are made ren'iovable. Each one is provided with a slot 23 near theend thereof into all of which the bar 20 is adapted to engage so to holdthe several blades in registering position. The ends of the blades 22are slanted or curved oil at A so that the connection between them andthe bar 20 may be made readily. Each of the ejecting blades is providedwith a plurality of small longitudinal grooves 25, preferably of.V-shape, on itsface so that each blade or section can be placed inposition to enter a mold space, being guided. by ridges 26 on a guideplate 27 along which the blades reciprocate.

In operation the member 16 is slid toward the mold in the usual mannerso that the ejector blades guided by the ridges 26, may pass into themold or into the several mold spaces and force the slug or slugstherefrom. As the mold is ordinarilvin vertical position'at this'timefthese slugs when several are formed, are forced out to the frontand between a couple of trimming knives and 31, the latter of which isremovable or adjustable as usual so as to provide for g one or moreletters or trimming slugs of difierent bodies. As they pass beyond thecutting edges of the blades they will. settle down into position on arest 6% site 32, preferably on the bottom of the knife 30; thus whenthey are delivered, the intervening spaces made by the mold dividingpieces are closed up. As the line'of slugs moves ior'ward as indicatedin Fig. '7, it comes between a, pair of gripper jaws and 34. The jaw 33is adjusted as by placing under it shims of different thick uesses. Thejaw 3 1- is mounted to swing on a pivot mounted on the delivery gripperv A spring 37 yieldingly holds this gripper jaw 3% in position to engageall the sings, it being understood that this jaw is of such length as toextend from the bottom to the top of the row' of slugs. The gripper jaw34: has a projection 38 adapted to engage the end of an adjustable screw89 mounted on a stationary part of the frame, so that when the deliv' rygripper moves up into position for gripping the slugs, the projectionwill come into contact with the screw and move the gripper javvBeoutwardly so as to permit the slugs to move between these jaws. N owwhen the deliverygripper 36 is moved back, the projection 38 recedesfrom the screw and this-allows the spring 37 to act immediately tobring-the jaw 34 into contact with the slugs to securely hold thembetween itself and the jaw 33.

A preferred manner. of operating the delivery gripper will now bedescribed. This gripper, it will be observed, has a gripper arm l0mounted to swing on a pivot 41 which in turn is supported by the regularlinotype vise 42. This vise is pivoted at the point 4-3 to the frame 4.4of the machine and is modified in shape to fit it for carrying thisgripper mechanism. It will be understood that it can be swung as a.whole about its pivot to make the mold gear or disk acces. sible fromthe front. The gripper arm 40 provided with a second arm 15 operated Vby a link 46. This link may be operated in any desired way but,is'shownn as having a yoke l7 operated by a cam 4-8. This cam ispreferably mounted on the regular cam shaft of the machine and developedto give an ordinary crank motion excepting that it has a slightdepression 480 to provide a slight dwell to hold the gripper quiet whilethe slugs are being 'lo'r arded into it as explained above. "lheswinging of the arm 40 from dotted to full line position in Fig. 2

operates the delivery gripper in the 'lollowing manner: This gripper ispivota'lly mounted on the end of the arm 40, by means f a. stud andyieldingly held up by a it is provided with a rearwardly projectingtailpiece 51 adapted to engage a stud 52 fixed to the vise 2.2. Now whenthe arm 4-0 moves to the dotted line position after the gripper issupplied with the line of slugs, itis obvious that the gripper arm w'519 to the position indicated in in Fig. 2,.so as to come intoregistration with the galley 53. l l hen the gripper reaches its extremeposition, a cam 54E on the galley will engage a pin connected with thegripping jaw 34- to turn the same so as to release the line ol'slugs anddeposit them in the galley. As the arm l0 starts to move back, the slugsleft in the galley are moved forward by a spring-pressed for wardingplate This accomplished by a cam 57 on the rear portion of theforwarding plate being engaged by a lug on the arm ll). The cam. andlug;- are so propon tinned that the movement of the forwarding plateequal to the width of the thickest slug east and as this movement isconstant, it. leaves the rear face of the sings in the same positionirrespective oi: their thickness. lit will be obvious, of course, thearm 10 swings rearwardly, the gripper 216 will be swung upwardly by thel 50, its motion being controlled by the cam shaped tail piece i=1.\Vhen it reaches a horizontal position there will still be a slightmotion of the arm 40 about its pivot. it is at this point that the abovementioned dwell occurs.

From a consideration of the above, it will be seen that a deliverymechanism is pro vide'd of such form that the first motion of the sameis directly away from the mold and that the delivery then has a compoundswinging motion about a moving pivot until it is b 'fpught into positionto deposit the slugs in the galley. While on the reverse motion, thecompound movement is used in 'such a way as rapidly to swing the gripperup into position in front of the mold from.

which it is moved directly toward the mold about the lower pivot l1 andis allowed to remain there while the slugs are being supplied to thedelivery mechanism. It will be seen also that while this delivery 'mechanism is especially adapted by reason of the long-faced gripper aws 83and to the divided mold type of slug casting machines, yet it is alsocapable of general use for ordinary linotype machines. it will be seenalso that the delivery mechanisnrdeseribed herein is especially adaptedfor the divided mold which has been mentioned and cooperates with thespecial ejector mechanism in an ellicient manner. 7

While I have illustrated and described a preferred form of theinvention, 1 am aware that many modifications may he made therein by anyperson skilled in the art without departing'from the scope of theinvention as expressed in the claims. Therefore, l. do not wish to belimited to the particular form shown, but
